Asbestos is a natural silicate mineral found in rocks. The properties of asbestos, such as its refractive indices, birefringence, retardation, extinction angle, pleochroism and sign of elongation, can be measured with a polarizing microscope. These optical properties, characteristic to all types of material, help in the identification of asbestos.

Nikon developed the LV100-UDM-POL/DS by equipping its high-performance polarizing microscope ECLIPSE LV100 POL with accessories that enable dispersion staining observations up to 400x .

Ideal for image recording of asbestos

The 5.0-megapixel DS-Fi1-L2 digital camera for microscopes is easy to use. The camera control unit has a built-in high-definition 8.4-in. LCD monitor and allows observation and recording without a PC. The large monitor and high frame rate of the camera boost operability. A 100-µm diameter concentric circle similar to an eyepiece graticule can be displayed for measurement. Two modes (red/blue) that allow imaging of asbestos with optimum color balance are available.

Combination example: DS-Fi1-L2 configured with ECLIPSE LV100-UDM-POL/DS
